The S4.04 Series Lapel system comes with a HM-33 Microphone, a state of the art Beltpack Transmitter and a UHF wireless diversity receiver. Featured is an Enhanced Frequency Bank system with up to 4 compatible licence free frequencies. All built on synthesised PLL quartz tuning technology. Fully utilises the limited space available on Channel 70 whilst maintaining guard bands to protect from adjacent channel interference. Simple easy lock system to synchronise multiple transmitters to receivers.
HM-33 Headworn Microphone
The HM-33 has been designed primarily for the active professional who needs hands-free operation. It remains in place and feels secure. Suitable for people in sports, journalism, event organising and presentations. The sound quality is pure and does not react to voices where sibilance would otherwise be a problem. It is comfortable to wear over extended periods. The HM33 is perfect for those applications which require a high performance cost-effective solution. Supplied with a black foam windshield

Channel 70 is Licence free.Wireless Microphones can tune into frequencies that do not require a licence to operate. There are several licence exempt areas for PMSE use. (Programme Making and Special Events)
The UHF licence exempt range is 863.100-864.900 MHz. This is within Channel 70 which has little spectrum assigned to it so limiting the number of users to four. The power is limited by legislation to 10mWatt. There is no limitation to how many frequencies can used in this channel as long as users stay within the confines of the band. More users could be squeezed in but that would jeopardise clear reception and interference from adjacent channels.
There are currently no plans to remove access to Channel 70; it will continue to be licence exempt for PMSE users.
Channel 70 is adjacent to use of mobile in the 800 MHz band. There should not be any interference however this is the risk taken with the licence exempt channels.
